The new function operates on any object that provides __geo_interface__
[link]. This release also fixes a major bug involving GEOS versions < 3.1 introduced in
1.2.2. You can download an sdist from http://pypi.python.org/pypi/Shapely/. Windows installers should be coming soon.

As I like to remind people every few releases, major portions of this work were
supported by a grant (for Pleiades) from the U.S. National Endowment for the
Humanities (http://www.neh.gov).

Update (2010-08-22): Win32 and Win-AMD64 installers have been uploaded to the locations above.
